Nowadays people are driving very fast, accidents are occurring frequently, we loss our valuable life by making small mistake while driving (school zone, hills area, highways). So to avoid such accidents, this project alerts drivers to control speed for appropriate place.
The main objective is to design a Smart Display and Controller meant for vehicle’s speed control and monitors, which can run on an embedded system. Smart Display & Control (SDC) can be custom designed to fit into a vehicle’s dashboard, and display information on the vehicle to be traveled in the different zone and its automatically controls vehicle’s speed in different zonal state (like school zone, hills area, U-turn, highway etc.).
The SDC is composed of two separate units: zone status transmitter unit and receiver (speed display and control) unit. The transmitter modules operate with a carrier frequency of 418MHz within the 260MHz-470MHz RF spectrum (unlicensed spectrum) thus avoiding any FCC charges or regulations. The wireless transmitter module can send data up to 100 feet away from the vehicle.
Once the information is received from the zones, the vehicle’s embedded unit is automatically alert the driver, to reduce the speed according to the zone, it waits for few seconds, otherwise vehicle’s SDC unit automatically reduce the speed.
In a critical situation many vehicles faces accident, due to this lot of person lost their lives. After that accident also some life can be saved but due to lack of information, time and place it may not be possible. Our project will provide an optimum solution to that draw back. According to this project when a vehicle met with an accident immediately the vehicle number and persons contact number will transferred to police control room or a rescue team. So the police can immediately trace the location from where the message came. Then after conforming the location necessary action will be taken.
